button / area on cover to launch display of pdf booklet

[kreativkod]

I have pdf booklets alongside my music files in a lot of directories. It would be nice to access them from the GUI. Could we have a feature button / area of cover art that launches the pdf from the GUI. Either hardcoded names, e.g. necessarily booklet.pdf, or simply any pdf in the directory and it would not work predictively with more than one pdf file.
